Insect shows resistance to Bt crops

Research output: Contribution to specialist publicationArticle

Abstract

A genetically modified cotton and maize crops were developed in 1996, that incorporates bacillus thuringiensis (Bt) to control pests like cotton bollworm. However, a team of University of Arizona entomologists discovered in recent study showed that the bollworms have now resistance to Bt crops. It is found that major pests attacking Bt crops have not evolved resistance. Addressing this issue, the UA researchers delay the resistance, where non-Bt crops are planted near Bt crops to provide "refuges" for susceptible pests. As a result, it showed that the bollworm resistance evolved fastest in the states with lowest abundance of refuges.
